    • A vibration attenuator seat includes a seat assembly with a pair of paralleled shafts slidable in horizontally positioned, ultra low friction, linear bearings mounted in a base assembly. A seat adjustment assembly has a bottom part which is a part of the base assembly and a latch in its top part for engaging the bottom part to lock the top and bottom parts in a plurality of positions. A pin secured to the top part of the assembly centers the seat assembly relative to the top part by being connected by one preloaded, closed-coil spring to one end of the seat assembly and by a second preloaded, closed-coil spring to the other end. The body of a shock absorber positioned parallel to the shafts is secured to the pin and the rod is secured to the seat assembly. The latch allows positioning adjustment of the seat assembly relative to the base assembly and the shock absorber attenuates shocks and vibrations between the base and seat assemblies while the springs provide preloaded biasing towards the adjusted position.
    • 振动衰减器座包括座组件,该座组件具有一对平行的轴,可在水平定位的超低摩擦直线轴承中滑动,安装在基座组件中。 座椅调节组件具有作为基座组件的一部分的底部和在其顶部的闩锁,用于接合底部以将顶部和底部部分锁定在多个位置。 固定到组件顶部的销钉通过一个预加载的闭合螺旋弹簧连接到座椅组件的一端并​​通过第二预加载的闭合螺旋弹簧连接到座椅组件的顶部部分 结束。 平行于轴定位的减震器的主体固定到销上,杆固定到座椅组件。 闩锁允许座椅组件相对于基座组件的定位调节,并且减震器减弱基座和座椅组件之间的冲击和振动,同时弹簧向调节位置提供预加载的偏压。

    • Assembly of the combustor dome in a gas turbine engine is facilitated by providing a self-fixturing configuration. The combustor dome assembly is made up of a dome plate having a plurality of swirler assemblies mounted therein. Each swirler assembly is provided with a locating pin that extends between the dome plate and the swirler assembly for positioning the swirler assembly with respect to the dome plate without the use of fixturing tools. Preferably, the swirler assembly includes a swirl cup and an outlet sleeve mounted in the dome plate. The locating pin is pressed into a hole formed in the swirl cup. One end of the pin is received in a slot formed in the dome plate, and the other end of the pin is received in a slot formed in the outlet sleeve. Thus, the locating pin sets the circumferential orientation of the swirler assembly in relation to the dome plate. A shoulder on the swirl cup sets the cup axially with respect to the dome plate, and a shoulder on the outlet sleeve sets the sleeve axially with respect to the swirl cup.
    • 燃气涡轮发动机中的燃烧器穹顶的组装通过提供自固定构型而被促进。 燃烧器穹顶组件由安装在其中的多个旋流器组件的圆顶板构成。 每个旋流器组件设置有定位销,该定位销在圆顶板和旋流器组件之间延伸,用于相对于圆顶板定位旋流器组件而不使用夹具。 优选地,旋流器组件包括旋转杯和安装在圆顶板中的出口套筒。 定位销被压入形成在旋转杯中的孔中。 销的一端容纳在形成在圆顶板中的槽中,并且销的另一端容纳在形成在出口套筒中的槽中。 因此,定位销相对于圆顶板设置旋流器组件的圆周方向。 旋转杯上的肩部将杯子相对于圆顶板轴向设置,并且出口套筒上的肩部将套筒相对于旋转杯轴向设置。
